Number that we find = A
A x 150/100=18
simplify 150/100=3/2
A x 3/2=18
divide both side by 3/2
A=18/(3/2)
A=18 x 2/3 
A=12
the number that 150% of it is 18 = 12

Answer:

x = 11

Step-by-step explanation:

∠BCE + ∠ECF = 180°

∴(10x + 15)° + 5x° = 180°

(15x + 15)° = 180°

15x = 180° - 15°

15x = 165°

x = 165°/15°

x = 11°

Clarissa works in sales for a software company. Her pay each month varies, because each month she receives a base pay of $2,400.
Pie

Answer:

Total earning of Clarissa for the november month is $3840 .

Step-by-step explanation:

As given

Clarissa works in sales for a software company.

Her pay each month varies, because each month she receives a base pay of $2,400.00 plus 8% commission on her sales.

During the month of November, Clarissa had $18,000.00 in sales.

8% is written in the decimal form

= \frac{8}{100}

= 0.08

Commission price = 0.08 × sales in november month .

                              = 0.08 × 18000

                              = $ 1440

Total earning in november month = Base price + Commission price

                                                         =  $2400 + $ 1440

                                                         = $ 3840

Therefore the total earning of Clarissa for the november month is $3840 .

Please help asap! I need this done tomorrow ​

Answer:

2x + 3y = 4

Step-by-step explanation:

The standard form:

Ax + By = C

So from the given form, arrange it to the standard form.

First, simplify the form by distribution.

y + 6 = -2/3(x - 11)

y + 6 = -2/3x + 22/3

Next, you make the fractions into whole by multiplying both sides by 3(this would eliminate all fractions).

(3)y + 3(6) = 3(-2/3x) + 3(22/3)

3y + 18 = -2x + 22

Now, arrange the "Ax" and the "C's".

3y + 18 = -2x + 22

2x + 3y + 18 = 22

2x + 3y = 22 - 18

2x + 3y = 4

Cheers!

Answer:

A) (-8, -16)

B) (0, 48)

C) (-4, 0), (-12, 0)

Step-by-step explanation:

A) the vertex is the minimum y value.

extremes of a function we get by using the first derivation and solving it for y' = 0.

y = x² + 16x + 48

y' = 2x + 16 = 0

2x = -16

x = -8

so, the vertex is at x=-8.

the y value is (-8)² + 16(-8) + 48 = 64 - 128 + 48 = -16

B) is totally simple. it is f(0) or x=0. so, y is 48.

C) is the solution of the equation for y = 0.

the solution for such a quadratic equation is

x = (-b ± sqrt(b² - 4ac)) / (2a)

in our case here

a=1

b=16

c=48

x = (-16 ± sqrt(16² - 4×48)) / 2 = (-16 ± sqrt(256-192)) / 2 =

= (-16 ± sqrt(64)) / 2 = (-16 ± 8) / 2 = (-8 ± 4)

x1 = -8 + 4 = -4

x2 = -8 - 4 = -12

so the x- intercepts are (-4, 0), (-12, 0)
